ROLL FOR CLOTHES WRINGERS Filed July 25, 1935 Patented Feb. 4, 1936 UNITED STATES PATENT OFFICE 2 Claims.

This invention relates to extractor rolls or wringer rolls, commonly employed in connection with washing and laundering machines.

An important object of the invention is to provide a roll of this character mounted on its shaft in such a way that the roll will be securely held in position at all times, eliminating any possibility of the roll working loose from its shaft under excessive pressure directed thereto during the pressing or wringing operation.

Another important object of the invention is to provide means at the ends of the rolls of a wringer to prevent the water or washing solution from entering the bearings and working parts of the-machine, and eliminating any possibility of the water or washing fluid picking up rust or grease and carrying it back into the water or washing fluid.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claims, it being understood that changes may be made in,the construction and arrangement of parts without departing from the spirit of the invention as claimed.

Referring to the drawing Figure 1 is an elevational view illustrating rolls constructed in accordance with the invention.

Figure 2 is an elevational view of a roll equipped with grooves at its ends for trapping water which would otherwise flow over the ends of the roll.

Figure 3 is an end elevational view of a roll, illustrating the square shaft opening thereof.

Figure 4 is an elevational view of one of the disks used at the ends of a wringer roll.

Figure 5 is a sectional view through the disk.

Referring to the drawing in detail, an upper wringer roll is indicated by the reference character 5, and the lower or cooperating wringer roll is indicated by the reference character 6.

These rolls are formed preferably with square openings for the reception of the shafts l which are also square in cross section, thereby providing means for securely fastening the rolls to their shafts without the necessity of cementing or otherwise. fastening the rolls on their shafts. While I have shown and described the shafts and openings of the rolls as square, it is to be understood that the shapes of these openings and shafts may be changed to meet the purpose of the inven tion, and to provide a positive drive between the shafts and rubber roll, without departing from the spirit of the invention.

As shown by Figure 1 of the drawing the rolls 5 and 6 are provided with pairs of annular grooves disposed adjacent to the ends thereof, the grooves 5 providing passageways to trap the water or washing fluid which is forced longitudinally of the rolls, .during the wringing or pressing operation thereof, thereby preventing the water or washing fluid from entering the bearings at the ends of the rolls, and which would ordinarily pick up rust and grease, and carry the rust and grease back into the washing fluid or water.

To further insure against the water entering the bearings and other moving parts of the machinery, I have provided disks 9 which may be constructed of any suitable material, the disks being positioned at the ends of the rolls and arranged in such a way that the disk of one roll will contact with the hub ID of the adjacent roll 20 providing a water tight connection between the contacting faces of the disks. While these disks are shown and described as removable, it is to be understood that these disks may be constructed as an integral part of the roll, should it be de- 5 sired to build them in this manner.

From the foregoing it will be seen that due to the construction shown and described, any water or washing fluid which would be forced laterally, will be trapped in the grooves 8 and 30 carried back into the tank. Any water or washing fluid which finds its way beyond the ends of the rolls, will be restricted in its movement to the bearings or other moving parts of the machine, by its contact with the disks 9 mounted at 35 the ends of the rolls.

Having thus described the invention, what is claimed is:

1. Wringer rolls embodying cooperating members, each member having annular grooves 40 formed in the periphery thereof and disposed adjacent to the end thereof, the grooves of one roll alining with the grooves of the adjacent roll and providing passageways, and cooperating disks on adjacent rolls disposed at the ends thereof for 5 restricting movement of water past the ends of the rolls.

2. Wringer rolls embodying cooperating members, said members having annular grooves at their ends, disks mounted at the ends of the rolls, the disk of one roll engaging the side face of the disk of the adjacent roll providing a fluid tight connection between the disks.
